Anyone Here Taking Linzess?

Lately I've been suffering from a very dry stool that's hard to pass. It's being caused by both my limited diet, I can't eat most veggies, and I simply don't usually eat fruit. It's also caused by the opiate meds I take for chronic pain. I am taking Colace but sometimes it helps and often it doesn't. I had never heard of Linzess until very recently.

All my life I suffered from IBS with diarrhea so the constipation the opiates cause is a welcome relief. But lately it's the dryness of the stool that causing the problem. I certainly don't want to go back to colon spasms and being on the bowel 6 times a day. So I'd like to hear any and all experiences anyone has had with Linzess?
